Impossible to upgrade...

Hi. I tried to upgrade my contract 3 times.... First I went into a Vodacom outlet. One consultant was at work with a client, one guy was behind the counter not doing much and not acknowledging me and a second consultant was floating around, looking around and looking lost. After standing at the counter for at least 5 minutes, they finally realised I am a potential client. They were unable to help me. The only person able to help was already busy with a client. I was not even offered a brochure to look through. I left. I tried the online upgrading on the website, and got an email which said a consultant will contact me within 24 hours with a reference number, 2 weeks later no-one contacted me. I called in, I had to ask repeatedly for the telephone consultant to repeat herself as I could not hear her she was speaking to fast. She told me rudely she could hear herself very well and therefore I should be able to hear her. I just cancelled my contract. I was offered free data when the consultant spoke to me about the cancellation. Sorry, too little, too late. Goodbye Vodacom.
